Beginning at 11:00am PST on November 17, you’ll be able to download and play Overwatch totally free whether you want to run it on PlayStation 4, Xbox One, or PC. Of course, the game’s free weekend can’t last forever. It will come to an end at 11:59pm PST on November 20.
It’s important to remember that since Overwatch is an online title, you will need a PlayStation Plus membership, Xbox Live Gold membership, or a Battle.net account if you want to actually play it. However, doing so will mean you receive access to the game’s full roster of 26 heroes, 16 maps, and various game modes.
If you decide to purchase Overwatch following the free weekend, you will also be able to keep all of the progress that you made over the course of the free weekend.
